Andreassen,Per Magnus,Øyvind Helgeland,Stefan Johansson,Stefan Johansson,Pål R. Njølstad,George Davey Smith,Alexandra Havdahl,Laura D Howe,Neil M Davies,Neil M Davies +19 more
TL;DR: In this paper, the authors used within-family Mendelian randomization, which accounts for familial effects by controlling for parental genotype, to investigate the impact of BMI on symptoms of depression, anxiety, and ADHD symptoms at age 8.

TL;DR: In this article, the structural and functional consequences of the recombinant C-terminus of HSC70-interacting protein (CHIP) variants were performed in vitro using ubiquitin ligase activity assay, circular dichroism assay and native polyacrylamide gel electrophoresis.
On the role of tribofilm formation on the alumina drive components of an ultrasonic motor
TL;DR: In this article, the authors investigated how the coefficient of friction between the drive pads and the drive rail depends on the number of strokes of the rail and found that the friction coefficient increases with the stroke count.
Low educational status is a risk factor for mortality among diabetic people
TL;DR: It is concluded that diabetic women have a very high relative risk for CHD mortality compared to non‐diabetic women, and diabetic people with a low attained level of education, have an increased vulnerability to, and a higher total mortality.
The role of the carboxyl ester lipase (CEL) gene in pancreatic disease.

TL;DR: The CEL gene has proven to be exceptionally polymorphic due to copy number variants of the CEL-CELP locus and alterations involving the VNTR, and is an attractive candidate gene for further exploration of links to pancreatic disease.
